TOP-ROLL CLEARER.

Application filed April 12, 1924. Serial No. 796,033.

To all whom it may concern.

Be it known that I, ERNEST C. Knyns, of IVhitinsville, in the county of Vorcester and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Top-Roll Clear-ers, of which the following is a full, clear, and concise description.

This invention relates to the class of devices for clearing the drawing rolls in textile machinery in which an endless band of cloth travels in rubbing contact with the surfaces of the top rolls, thus maintaining the rolls in proper working condition.

I-Ieretofore in drawing frames equipped with a plurality of draw-boxes, each box had a travelling endless band clearer held in a frame mounted in the cover of the box, motion being imparted to all clearers simultaneously by a shaft extending the length of the frame at the back of the draw-boxes. Whenever it was desirable to remove a clearer cloth and replace with another it was necessary to remove this shaft and the covers of all the draw-boxes, thus causing con siderable work on the part of the operatives and a loss in the productive capacity of the machine during the resulting stoppage.

The object of my invention is to provide a construction whereby the above faults are remedied.

In carrying out my invention, I provide a clearer driving shaft made up in sections, one for each clearer connected together in such a manner that a clearer may be removed without disturbing the others.

In the accompanying drawings: Figure 1 is a cross section, 011 line 22 of Figure 2, of a draw-box as ordinarily constructed showing the clearer and its relations to the top rolls and the cover of the draw-box, the clearer being shown in operating position in full lines and in inoperative position in dotted lines. Figure 2 is a partial plan view of a number of draw-box covers, two of which are shown in their normal closed operating position and the other in an open position ready for the removal of its clearer. Figure 3 is an enlarged sectional elevation on line 33 of Figure 4 showing the clearer driving shaft in its bearing. Figure 4 is a plan view of the shaft coupling in its bearing with cap removed. Figure 5 is an enlarged view of a removable section of the clearer driving shaft.

In the drawings, 1 represents a roll stand supporting the bearings of the drawing rolls 2 and their respective top rolls 3; 4i is the endless clearer cloth belted on the roll 5 and driving shaft 6. The roll 5 is supported in adjustable bearings of common construction fastened to the underside of the draw-box clearer cover 7. The clearer driving shaft 6 is supported in bearings 8 fixed on top of the roll stands 1, it being maintained in each bearing by a cap 9. The shaft 6 is made up of a plurality of sections, one for each drawboX, coupled together in the bearings by loosely fitting male and female joints as plainly shown in Figures 4 and 5. By this construction one section may be removed without disturbing the others. Rotary motion is imparted to the shaft through the gear 10 connected with the usual driving gearing, (not shown) of the machine.

Each clearer cover with its clearer cloth is in a swinging relation with the top rolls by being fixed to bearings 11 loosely mounted at each end of a section of driving shaft. By this construction the clearer, its driving means and cover form a complete unit which is readily removable as a whole from the machine by simply taking off the bearing caps 9 and lifting the whole unit from its normal position in the machine after which the cloth may be easily removed and replaced by another.

What I claim is:

1. In a machine of the character described, the combination of a plurality of travelling endless band top roll clearers, a shaft for simultaneously imparting motion to the clearers comprising individual sections for each clearer, and means for coupling the sections together.

2. In a machine of the character described, the combination of a plurality of travelling endless band top roll clearers, a shaft for simultaneously imparting motion to the clearers comprising individual sections for each clearer, male and female joints for each section of the shaft, bearings supporting the shaft at the joining of the sections and removable caps to maintain the shaft in the bearings.

3. In a machine of the character described, the combination of a plurality of travelling endless band top roll clearers, a shaft for simultaneously imparting motion to the clearers comprising individual sections for each clearer, male and femalejoints for each section of the shaft, bearings supporting the shaft at thejoints of the sections, and means for maintaining the shaft in its bearings.

In testimony whereof, I have signed this specification.
